Just one month after the overthrow of Egypt's first democratically elected president, Mohamed Morsi, the country is again facing uncertainty over its future.

This week, security forces violently attacked Morsi supporters, who were attacked at encampments near Cairo where they had been calling for the former president's return to power. The death toll from the attack is at 525 – and rising.

The US has strongly condemned the violence and is facing pressure to suspend aid to Egypt's military as the number of casualties and injuries continues to mount.

Join Spencer Ackerman and Martin Chulov on Friday afternoon for a Q&A on the crackdown, the country's future and the role of the US in the ongoing crisis.

Martin is an expert on the middle east who has reported extensively from Egypt and Syria for a number of years. Spencer is national security editor of Guardian US and will be able to provide context on the role of the US in the ongoing crisis.

He did not respect the law or the constitution he swore he would protect, He issued a constitutional decree to consolidate his powers and force a constitution that alienated most of the Egyptian people. In brief he tried to impose his brotherhoods ideology on people who did not accept it, he alienated the opposition and never compromised on anything. Furthermore he was trying to put his people in key positions to rig all the coming elections. The opposition and the army gave him several chances to change his position but he never listened. By the way, I voted for him but I turned against him since he issued his constitutional decree. If the president does not respect the law, how can you expect any one else to respect it.
